Jude warns his readers by describing the polluting influence of the “certain men” on the Church’s holy feasts, their self-serving nature, their empty promises, their hypocritical lives, their shameful lifestyle, and most importantly, their dire destiny.

It seems that Jude is maxing out the “fear-threat” approach to reach the infiltrators—and anyone who is even remotely impressed or persuaded by them.
